Lean production is an integrated socio-technical system whose main objective is to eliminate waste by concurrently reducing or minimizing supplier, customer, and internal variability. This dimension of lean production is about facilitating JIT production including kanban cards which serves as a signal to start or stop production.

Please indicate the extent of implementation of each of the following practices in your plant. (1) no implementation; (2) little implementation; (3) some implementation; (4) extensive implementation; (5) complete implementation.

Production is "pulled" by the shipment of finished goods.

Production at stations is "pulled" by the current demand of the next station.

We use a "pull" production system.

We use Kanban, squares, or containers of signals for production control.
